The following function restricts the amount of the characters in the inputBox / textField AKA [Edit] to "N" characters maximum. The characters which will be entered in the Edit after the limit - will be deleted automatically.

The function:

Code:

function limitInputTo3Chars(Sender,Key,KeyChar,Shift)
{
         var n = 3
         if (Sender.Text.length > n)
         {
            Sender.Text = Sender.Text.substring(0, n);
         }
}

Add the function name to the textBoxes' "OnKeyUp" event
